GCSE GCSE Edexcel Foundation: June 2018 Paper 3, Q19 The scatter diagram shows information about rainfall and temperature on 12 days. It shows the age of each boy and the best time she takes to run 100 metres. 1 The scatter diagram shows information about rainfall and temperature on 12 days. It shows the age of each boy and the best time she takes to run 100 metres. Temperature (°C) Temperature (°C) Rainfall (mm) Rainfall (mm) (a) Write down the type of correlation (a) Write down the type of correlation (1) (1) On another day it is 21 °C. The total rainfall that day is 22 mm. The point representing this information would be an outlier on the scatter diagram. (b) Explain why. On another day it is 21 °C. The total rainfall that day is 22 mm. The point representing this information would be an outlier on the scatter diagram. (b) Explain why. On a different day the rainfall is 26 mm. Jerry says “The scatter diagram shows it should be more than 21°C on that day.” (c) Comment on what Jerry says. (1) On a different day the rainfall is 26 mm. Jerry says “The scatter diagram shows it should be more than 21°C on that day.” (c) Comment on what Jerry says. (1) (1) (1) (Total for Question 1 is 3 marks) (Total for Question 1 is 3 marks)
